ANgular:NgFor中的mat列表仅支持绑定到Iterables(如数组)

TS:

export class ListaEventiComponent implements OnInit {
  results:EventoServer[] = []
  constructor(  public dialogRef: MatDialogRef<ListaEventiComponent>,
    @Inject(MAT_DIALOG_DATA) public data:EventoServer[] ) {
      this.results = data
      console.log(this.results)
     }

  ngOnInit(): void {
  }

}

<div class="row d-flex justify-content-center">
  <mat-list>
    <mat-list-item *ngFor="let evento of results | keyvalue">
      {{evento.descrizione}}
    </mat-list-item>
  </mat-list>
  </div>
